Yearly Science Review

What is an observation?

• A guess about what will happen in an experiment

• Information collected using the senses or tools

• A step that comes after the conclusion in an experiment

• A question that cannot be answered with evidence

Which of the following is an example of a hypothesis?

• The plant grew 3 inches in two weeks.

• If plants receive more sunlight, then they will grow taller.

• I recorded the height of the plant every two days.

• The plant was green and had five leaves.

What is the purpose of an experiment?

• To test a hypothesis by gathering data

• To find the correct answer to any science question

• To guess what will happen in the future

• To make a scientific model

What is a variable in an experiment?

• The result of the experiment

• The part of the experiment that never changes

• A factor that can be changed or measured

• A tool used to record data

What is the independent variable in an experiment?

• The factor that is being changed on purpose

• The factor that is being measured

• The factor that stays the same

• The final result of the experiment

What is a conclusion in a scientific investigation?

• A summary that explains what was learned from an experiment

• A guess about what will happen next time

• The tools used to conduct the experiment

• The process of recording observations

Why is data important in an experiment?

• It helps scientists prove their opinions.

• It provides evidence to support or reject a hypothesis.

• It makes an experiment more fun.

• It is the only part of an experiment that can change.

What is scientific evidence?

• Information collected from personal opinions

• Facts and data that support a claim or conclusion

• Predictions about what will happen in an experiment

• The guess made before an experiment begins

What is a scientific model?

• A smaller or larger representation of something used to study it

• A set of rules that scientists must follow

• A real-life version of an experiment

• A random guess about how something works

What is a prediction in science?

• A guess made with no evidence

• A statement about what might happen based on past experiences or data

• The final step in an experiment

• The factor that is changed on purpose in an experiment
